To all whom it may concern:

Be it known that I, Hnmn: Plnrnn, a sub Ject ot the King of Belgium, residing at Liege, Belgium, have invented certain new and useful Improvements in Motor-Vehicles, of which the following is a specification, reference being had to the drawings accompauye v ing and forming apart of the same.

The operation of a vehicle of this character iswell understood to be as follows :--l irst the dynamo is started as a motor by current from the secondary battery. Motion is in thisway imparted to the engine which is thus started in operation, and, when its power increases to a certain degree, drives the dynamo a generator, any excess of power being stored as electrical energy in the battery until the counter electromotive force of the latter exceeds the electromotive force of the dynamo, when it again absorbs energy and runs as a motor to assist the engine. By this system the speed of the vehicle is anti matically regulated while the stored energy 7 in the battery is at all times available to start and to back the vehicle. In vehicles equipped with this system heretofore, the engine and dynamo-motor have been rigidly coupled by means of a shaft, but as the combined length of the set comprising'the ehgine and dynamo-motor is greater than the practical width of the vehicle, a direct drive of the latter is not possible. This is a disadvantage, particularly in the case of high power vehicles, in which, as is well known,.

increased power of that obtainable with a given diameter of cylinder,-'can only be socured by increasing the number of cylinders. A further objection to the system as hcrcto fore applied, resides in the necessity for using bevel gears as the means of transmit- 'ting the power.

The object of my present invention is to providefor a direct drive in all kinds of Selfpropelled or motor vehicles of the class hereinbei'ore referred to, and to so construct and arrange the same that either or both the engine and the dynamo-motor may occupy the entire width of the vehicle if so desired.

Application filed January 25, 1907. Serial at. 353,975.

To this end my invention consists inconneclm-g the engine to the dynamo-motor by means of therails or the surface over which the vehicle travels, or by which it is supported, and thus to avoid the use of a connectin r shaft or direct coupling, while still maintaining the two elements. in constant connection and iliter-dependent, but solely through the surface connection.-

. 6) My improvements are illustrated in the accompanying drawings, in which-- Figure l is a partly diagrammatic and plan view of the application of the same to a rail motor vehicle.

vention as applied to a'rail motor vehicle, and Fig. 3 is-a similar view partly in elevation of a road motor vehicle. i I

"in carrying my invention into effect, as 7 applied to 'a. rail vehicle, Imount the engine, shown in this instance in Fig. 1 as a single cylinder engine, so that its piston rod 2 operates the crank shaft 3 of the wheels 4 and 5. 6 and 7 is mounted the dynamo-motor, which may be of suitable form of shunt Wound dynamo, and in series therewith is the secondary battery 10 and a controller 11 ar-- ranged in the usual manner to effect for- 35 ward or reverse rotation of the dynamo at such speeds as may be desired. It will thus be seen that the only connection between the engine and the dynamo-motor is through the ails 12 and 13.

\Vith reference to the arrangement illustrated in Fin. 2; the engine 1 drives theshalit 3 of the main pair of wheels 4. .l-hrough the rails 12 other pairs of wheels 1.4, 15, 16'and 17, suitably mounted in trucks 9'5 22 and 23, are connected to the main wheels -?t in the same manner as above described, and dynamo-motors 18 to 21 are mounted on the axles of wheels It to 17. Such an arrangement may be used to propel or draw a series of cars, if desired, and is especially adapted for heavy vehicles, or for service requiring frequent starting, rapid braking, and a moderate running power, because,

anion other reasons at startin when maxig a e Fig. 2 shows in ele- 7O vation and diagram a modification of the m On the shaft 8' of the other wheels 30 The surface coupling of the en 'no and is directly connected to one element of a mixed set. 25' which are preferably the front wheels, but which'may be either the front or rear Wheels, are on axles upon which are mounted the dynamo-motors 26 and 27 respectively, and the axles of wheels 28 and 29 are crank shafts driven bythe pistons of the cylinders 30 "and 31 respectively. The only connection betweenthe engine and the dynamorhotors, however, is through the surface of the road, but when thus connected the operation of the system is similar to, that above described.

Having now described my invention, what I. claim 1s:

1.v In a motor vehicle, the combination with an internal combustion engine connected with adriving wheel of the vehicle to drive the vehicle, ofa dynamo-motor con- .nected to another driving wheel of the vehicle to drivethe vehicle and devoid of mechanical actuating connection with the engine save through the said driving wheels "and the roadway on which the latter run, and a secondary battery connected with the dynamo-motor to deliver current to vor re- For example wheels 24 and ceive current from the dynamo-motor according as the speed of the .vehicle varies from a predetermined rate.

2. n a motor vehicle, the combination of a a pair of drlving Wheels, internal combu'stion driving-means connected to said wheels to drive the same, a pair of comblnedsteering-and-driving wheels, dynamo-motors conconnection with the said internal-combustion driving-means save through the roadway on which the vehicle runs, and a secondary battery connected with the dynamo-motors to deliver current thereto or receive current therefrom according as the speed of the vehicle varies from a predetermined rate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
